434126 ÷ 91 
The aim is to understand the frequency of 91 in 434126.

Going ahead to step 1:
4 divided by 91 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 91

Let's proceed to step 2:
43 divided by 91 is 0 with a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Bring next digit (4) of the dividend behind the 43 and repeat the process: 434 / 91

Going ahead to step 3:
91 goes into 434 4 times with a remainder of 70.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 364 from 434 to get 70.
Take the next digit (1) from the dividend and append it to 70, then repeat: 701 / 91

Let's proceed to step 4:
91 can be fit into 701 7 times, resulting in a remainder of 64.
Record the quotient 7 as the next digit in the result. 
Result so far: 47.0
Deduct 637 from 701 and we're left with 64.
Bring next digit (2) of the dividend behind the 64 and repeat the process: 642 / 91

Advancing to step 5:
91 can be fit into 642 7 times, resulting in a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 477.0
The remainder is 5 after subtracting 637 from 642.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 91

Step 6:
91 goes into 56 0 times with a remainder of 56.
Record the quotient 0 as the next digit in the result. 
Result so far: 4770.0
The remainder is 56 after subtracting 0 from 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 7:
When dividing 560 by 91, we get 6 with a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 4770.6
If we subtract 546 from 560, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 8:
The number 91 fits into 140 1 times, leaving a remainder of 49.
Put 1 as the next digit of the answer. 
Result so far: 4770.61
If we take 91 away from 140, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 9:
When dividing 490 by 91, we get 5 with a remainder of 35.
The next digit of our result is 5. 
Result so far: 4770.615
If we take 455 away from 490, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 10:
When dividing 350 by 91, we get 3 with a remainder of 77.
Record the quotient 3 as the next digit in the result. 
Result so far: 4770.6153
Deduct 273 from 350 and we're left with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Let's proceed to step 11:
770 divided by 91 is 8 with a remainder of 42.
The next digit of our result is 8. 
Result so far: 4770.61538
Subtracting 728 from 770 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 12:
420 divided by 91 is 4 with a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 4770.615384
If we take 364 away from 420, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 13:
91 goes into 560 6 times with a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 4770.6153846
Deduct 546 from 560 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 14:
The number 91 fits into 140 1 times, leaving a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 4770.61538461
Subtract 91 from 140 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

After the division, we end up with 4770.61538461 and a remainder of 4.9e-08.
